When a copper ball is heated, the largest percentage increase will occur in its
- ADiameter
- BArea
- ✓Volume
- DDensity
✓
Answer
Correct option: C.
Volume
c
(c) When a copper ball is heated, it’s size increases.
(c) When a copper ball is heated, it’s size increases.
As Volume $\propto(radius)^3$ and Area $\propto ((radius)^2$, so percentage increase will be largest in it’s volume.
Density will decrease with rise in temperature.
